The minimum breakdown voltage of 99.45 V provides the trigger threshold — once the transient pushes the rail above that, the device avalanches and shunts the surge current to ground. ## What the ratings mean for the circuit For shorter pulses (e.g. 8/20 µs), the peak power capability is higher; for longer or repetitive surges, derate accordingly. The clamping voltage of 159.6 V at 10 A is the maximum voltage the protected rail sees during the surge. If the downstream circuitry (e.g. a 100 V-rated DC-DC converter input) cannot tolerate that peak, a lower-clamping TVS or additional input filtering is needed. The junction temperature derates the peak pulse power above 25°C per the standard TVS derating curve (not reproduced here). The DO-201AA (DO-27) axial leaded package is a through-hole form factor with a 0.052-inch diameter lead. It mounts into a 0.040-inch plated through-hole on the PCB. The axial leads are typically bent to a 0.400-inch lead spacing for insertion. The tape and reel packaging is suitable for automated insertion but the part is obsolete, so reel quantities are limited to available surplus lots.","metaTitle":"Littelfuse 1.5KE110C TVS Diode, 1500W, 94V Standoff, DO-201","metaDescription":"Obsolete Littelfuse 1.5KE110C bidirectional TVS diode. 1500W peak pulse power, 94V reverse standoff, 159.6V clamping.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Littelfuse Inc.","Type":"Zener","Series":"1.5KE","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Obsolete","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Voltage - Breakdown (Min)":"99.45V","Voltage - Clamping (Max) @ Ipp":"159.6V","Voltage - Reverse Standoff (Typ)":"94V","Current - Peak Pulse (10/1000µs)":"10A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7081","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f1ea870152ad203d90f672f2af1c1ed0.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What does the 94 V reverse standoff voltage mean for my circuit?","answer":"The 94 V reverse standoff is the maximum DC voltage the TVS can withstand without conducting significant leakage.
